Suppose that you are given two sets of samples with the following information:
(a) Estimate a linear regression equation for each sample separately and for the pooled sample. (b) State the assumptions under which estimation of the pooled regression is valid. (c) Explain how you will test the validity of these assumptions using the data provided.
Suppose that you are given two sets of samples with the following information: (a) Estimate a...

Suppose you are asked to estimate the 1st quartile (25% point) from a distribution. You are given a sample of size 30: 7.34 8.16 8.69 8.80 8.82 9.28 9.29 9.38 9.43 9.51 9.65 9.78 9.84 9.95 9.98 9.99 10.02 10.05 10.37 10.42 10.52 10.67 10.78 10.87 11.05 11.12 11.19 11.37 11.54 11.92 Given sorted here. A. If I just tell you the data is an iid (independent and identically distributed) sample from a distribution, reasoning based on the confidence intervals...
Problem 4. A researcher is comparing the effectiveness of two sets of instructions for assembling a book shelf A sample of 24 college students is obtained, and each participant is randomly assigned to one of the two groups. Half of the participants (n 12) are given both written and graphic instructions ("Written Graphic"), and the other half (n= 12) receives written instructions only ("Written"). The researcher measures how much time is needed for each participant to assemble the book shelf...
You did not receive full credit for this que Suppose you have the information shown in the table below about the quantity of a good supplied and demanded at various prices Price (S) Quantity demanded Quantity supplied 180 50 40 30 20 140 100 60 20 40 20 10 60 80 a. Draw the demand and supply curves from the data provided. Instructions: Use the tools provided (D1 and S1) to plot the demand curve (5 points total) and the...
Can somone show me how to do the 1st problem? Need to
find the LS and SS for the fit and the LH and SH for the hole.
Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...

3. Answer the following question for where Y has been regressed on X1, X2, and X3. Use the linear regression output in the Excel file. Your answers should be rounded to 2 decimal places. a. What is the equation for the line of best fit or regression line? b. The proportion is for the amount of the variability of Y that is explained or accounted for by the model. C. The correlation between...
